Bag chip means that some luxury brands choose to put an anti-counterfeiting electronic chip on their goods before they are put on the shelves, in order to crack down on counterfeit goods. With the chip version, consumers can distinguish genuine goods from counterfeit goods through the anti-counterfeiting chip in their bags.

in addition, these "invisible" chips may be hidden in trademarks, stitches, or bags. Consumers only need to scan the label of the bag with the first app installed on the mobile phone, and they can distinguish the authenticity. However, the cost of this anti-counterfeiting technology is high, so at present, only some famous big brands have launched chip versions of luxury goods.
